Protect Attorney-Client Privilege
with Enterprise-Grade Cybersecurity

Attorney-client privilege is the foundation of legal practice, and a cybersecurity breach can destroy it. When privileged communications are exposed through a data breach, courts may find that the privilege has been waived if the firm failed to take reasonable precautions to maintain confidentiality. In an era of cloud-based practice management, mobile devices, and remote work, "reasonable precautions" requires far more than a firewall and antivirus software.

We begin with a comprehensive data classification exercise that identifies every category of sensitive data your firm handles: privileged communications, attorney work product, client personally identifiable information (PII), protected health information (PHI) for healthcare litigation, financial records, trade secrets, and intellectual property. Each category receives appropriate security controls based on its sensitivity level and regulatory requirements.

Our implementation includes end-to-end email encryption, document management system security hardening, role-based access controls tied to matter assignments, data loss prevention (DLP) rules that prevent privileged content from leaving approved channels, and comprehensive audit logging that creates a defensible record of who accessed what data and when. These controls collectively satisfy ABA Formal Opinion 477R's requirement for reasonable efforts to protect client information transmitted electronically.

Electronic discovery is one of the most data-intensive and security-sensitive processes in legal practice. Firms routinely collect, process, review, and produce millions of documents containing the most sensitive information their clients possess. A security failure during e-discovery can result in spoliation sanctions, privilege waiver, data breach notification obligations, and malpractice claims.

Our digital forensics team, led by Licensed Digital Forensic Examiner Craig Petronella, implements secure e-discovery workflows that maintain defensible chain of custody from preservation through production. We deploy encrypted collection tools, secure processing environments with access controls, privilege review platforms with audit logging, and production protocols that ensure only properly designated documents leave your firm's control.

For firms that handle e-discovery in-house, we secure your Relativity, Concordance, or other review platform environments. For firms that outsource to e-discovery vendors, we conduct third-party security assessments to ensure your vendors meet the same standards your ethical obligations demand. Every step is documented to withstand challenges to evidence authenticity and chain of custody.

Ransomware attacks against law firms have exploded in recent years. According to the FBI and CISA, the legal services sector consistently ranks among the top five most-targeted industries. The reason is simple: law firms face court deadlines, statute of limitations pressure, and client obligations that make them more likely to pay ransoms quickly. Modern ransomware groups also practice double extortion — encrypting your data while simultaneously threatening to publish stolen client files on the dark web.

For a law firm, a ransomware attack is not just a business interruption. It is a potential ethical violation. If ransomware encrypts client files before a filing deadline, you face both malpractice exposure and potential bar discipline. If stolen client data is published online, you have triggered data breach notification obligations in every state where affected clients reside, plus potential class action liability.

We implement comprehensive ransomware defenses including advanced endpoint detection and response (EDR) on every workstation and server, email security gateways that catch phishing and malicious attachments before they reach attorneys, network segmentation that limits lateral movement, immutable backup systems that cannot be encrypted by ransomware, and tested business continuity plans that get your firm back online within hours rather than weeks. Our incident response team provides 24/7 coverage to contain and remediate attacks before they spread.

ABA Formal Opinion 477R makes clear that unencrypted email is generally insufficient for transmitting highly sensitive client information. Many state bar ethics opinions have reached the same conclusion. Yet most law firms continue to send privileged documents as unencrypted email attachments, creating risk with every message. Sophisticated clients, particularly in financial services, healthcare, and government contracting, increasingly require their outside counsel to use secure communication platforms as a condition of engagement.

We deploy encrypted client portals that provide a professional, branded experience for secure document exchange. Each portal features multi-factor authentication, granular per-matter access controls, automatic expiration of shared files, comprehensive download audit logs, watermarking for sensitive documents, and mobile device support for clients and attorneys on the go. These portals integrate with your existing practice management and document management systems to minimize disruption to attorney workflows.

For firms that need more than portal-based sharing, we implement secure large file transfer solutions for e-discovery productions, virtual data room capabilities for M&A transactions, and encrypted messaging platforms for real-time privileged communications that satisfy the "reasonable efforts" standard under ABA Model Rule 1.6(c).

Law firms that represent defense contractors, serve as outside counsel to the Department of Defense, or handle litigation involving Controlled Unclassified Information (CUI) face a unique compliance challenge. The CMMC 2.0 framework requires all organizations in the defense supply chain — including law firms — to demonstrate appropriate cybersecurity maturity levels when handling CUI. If your firm receives CUI from a defense contractor client in connection with litigation, contract review, or regulatory matters, CMMC requirements may apply to your firm.

Craig Petronella holds the CMMC Certified Registered Practitioner (CRP) credential from the Cyber AB. We guide defense litigation firms through the CMMC compliance process including gap assessment against NIST SP 800-171 Rev 3 requirements, System Security Plan (SSP) development, technical control implementation, CUI enclave architecture, and mock assessment preparation. Our approach minimizes the scope of your CMMC assessment by creating a defined CUI processing environment separate from your general firm network.

For firms handling ITAR-controlled technical data in connection with defense litigation, we implement additional export control protections including US-person-only access restrictions, compliant cloud environments, and data loss prevention controls that prevent unauthorized transfer of controlled technical information.

Criminal defense attorneys who access FBI Criminal Justice Information Services (CJIS) data — including criminal history records, arrest reports, and law enforcement sensitive information — must comply with the FBI CJIS Security Policy. This policy mandates specific technical controls including advanced authentication, encryption at rest and in transit, audit logging, personnel security screening, and incident response capabilities. Non-compliance can result in loss of access to CJIS data, which directly impairs your ability to represent criminal defense clients.

We implement CJIS-compliant environments for criminal defense practices including multi-factor authentication meeting CJIS Advanced Authentication requirements, FIPS 140-2 validated encryption for all CJIS data at rest and in transit, comprehensive audit logging with minimum 1-year retention, personnel security screening documentation, and security awareness training for all staff with CJIS access.

Our CJIS implementation integrates with your existing firm infrastructure while maintaining the strict separation of CJIS data required by the FBI policy. We handle the technical assessment, security plan documentation, and ongoing compliance monitoring so your criminal defense attorneys can focus on representing their clients.

When a law firm experiences a data breach, the response is uniquely complex. Unlike most businesses, your breach notification obligations extend beyond standard state data breach laws. ABA Model Rule 1.4 requires prompt notification to affected clients. State bar ethics rules may impose additional reporting obligations. If the breach involves data from clients in regulated industries, those regulations may also apply. Meanwhile, you must preserve privilege over your own incident response communications while simultaneously containing the breach and preserving forensic evidence.

Our data breach forensics team provides rapid response within hours of detection. Craig Petronella, a Licensed Digital Forensic Examiner, leads forensic investigations that produce court-admissible evidence and defensible findings. We identify the attack vector, determine the scope of data exposure, contain the breach, preserve evidence with proper chain of custody, and provide the forensic analysis your firm needs to meet notification obligations and defend against subsequent claims.

We also assist with the multi-layered notification process that law firm breaches require: state attorney general notifications, individual client notifications, bar regulatory body reporting, and notifications to clients' regulators when the breach affects regulated data. Our incident response retainer ensures your firm has access to immediate forensic expertise without the delays of procurement during a crisis.

Security assessments and compliance audits verify that controls are in place. Penetration testing proves they actually work. Our penetration testers simulate the tactics, techniques, and procedures used by the threat actors who target law firms: phishing campaigns crafted to look like court notices or client communications, attacks against client portals and VPN gateways, exploitation of unpatched practice management systems, and social engineering targeting attorneys, paralegals, and administrative staff.

We conduct external penetration testing against your internet-facing systems, internal penetration testing to assess what an attacker could access after compromising an endpoint, web application testing of client portals and firm websites, wireless security assessment, and targeted phishing exercises. Every finding is prioritized by risk level and mapped to the specific ABA ethical obligations it could implicate.

Our ongoing vulnerability management service provides continuous scanning, patch management, and quarterly penetration testing to ensure your defenses keep pace with evolving threats. Many cyber liability insurance policies now require regular penetration testing, and sophisticated clients increasingly include pen test results in their outside counsel audit questionnaires.
